SCM1240M  
High Voltage, High Current 3-Phase Motor Drivers  
Features and Benefits  
Description  
Each half-bridge circuit consists of a pre-driver circuit that  
is completely independent from the others  
10 to 30 A continuous output IPM in a small-footprint  
package  
Protection against simultaneous high- and low-side turning on  
Bootstrap diodes with series resistors for suppressing  
inrush current are incorporated  
TheSCM1240Minverterpowermodule(IPM)devicesprovide  
a robust, highly-integrated solution for optimally controlling  
3-phase motor power inverter systems and variable speed  
control systems used in energy-conserving designs to drive  
motors of residential and commercial appliances. These ICs  
take 85 to 253 VAC input voltage, and 10 to 30A(continuous)  
output current. They can withstand voltages of up to 600 V  
(IGBT breakdown voltage).  
CMOS compatible input (3.3 to 5 V)  
Designed to minimize simultaneous current through both  
high- and low-side IGBTs by optimizing gate drive resistors  
Integrated Fast Recovery Diode (FRD) as freewheeling  
diode for each IGBT  
UVLO protection with auto restart  
Thermal shutdown (TSD) with auto restart  
The high current SCM1240M employs a new, small-footprint  
proprietary DIP package. The IC itself consists of all of the  
necessary power elements (six IGBTs), pre-drive ICs (three),  
and freewheeling diodes (six), needed to configure the main  
circuit of an inverter, as well as a bootstrap circuit (three  
bootstrap diodes and three boot resistors) as a high-side drive  
power supply. This enables the main circuit of the inverter to  
be configured with fewer external components than traditional  
designs.  
¯¯¯  
Fault (FO indicator) signal output at protection activation:  
UVLO (low side only), OCP, STP, and TSD  
Proprietary power DIP package  
UL Recognized Component (File No.: E118037)  
Applicationsincluderesidentialwhitegoods(homeappliances)  
and commercial appliance motor control, such as:  
Air conditioner compressor motor  
Air conditioner fan motor  
Packages: Power DIP
